OUR SERVICES

FOUNDATIONS & POURED CONCRETE WALLS
We pour precise foundations and structural walls built to handle Michigan’s soil and weather conditions. From engineered footings to full basement walls, every pour is measured, level, and built to last.

EXCAVATION
Our crew manages site excavation, trenching, and soil removal with care and accuracy. Whether it’s a tight residential build or a large commercial site, we dig clean, maintain grade, and stay ready for the next phase.

WATERPROOFING & DRAINAGE
Rain and freeze-thaw cycles are no match for our waterproofing systems. We install membranes, drain tile, and moisture barriers that keep foundations dry and protected for years to come.

WHAT YOU NEED TO KNOW
Foundations Designed for Ann Arbor’s Development Pattern
From innovative developments along the Huron River to family homes in the Kerrytown and Burns Park neighborhoods, Ann Arbor is a hub of academic, cultural, and residential expansion. Robust, expertly designed foundations are crucial to sustain this vibrant progress. Our cast-in-place concrete walls and foundational systems are engineered for upscale residences and institutional builds — delivering accuracy, resilience, and enduring reliability.
Discover Ann Arbor’s Planning and Development resources to keep informed on municipal construction standards and expansion initiatives.
Soil, Drainage & Foundation Success
Ann Arbor’s diverse subsurface — ranging from dense glacial till to permeable alluvial deposits — requires meticulous foundation design. Poor site prep or inadequate drainage can lead to settling, heaving, or structural distress in footings and retaining walls. Our expertise includes precise earthwork, stabilized subgrades, and membrane protection to ensure sustained integrity for residential estates, educational facilities, and civic developments.
Access authoritative construction standards via the City of Ann Arbor Building and Safety Division.
Why Local Ground Conditions Matter
Constructing in Ann Arbor involves navigating variable loamy clays, undulating topography, and flood-prone zones adjacent to the Huron and nearby wetlands. These factors call for thoughtful strategies, spanning cut-and-fill operations to final compaction. We’ve executed numerous basement and perimeter wall installations in areas like the Old West Side, near Geddes Pond, and along the Allen Creek watershed — tailoring solutions for seismic resilience and hydrological balance in this dynamic landscape.
Consult the Ann Arbor Planning Department for regulations on land division, approvals, and compliance standards.
Strategic Foundation Work Near Key Corridors
Our concrete installations span Ann Arbor’s prime development zones — encompassing the bustling downtown core, the US-23 corridor, innovation hubs along Plymouth Road, and revitalized segments of State Street. From industrial footings adjacent to Ellsworth Road to crawlspace reinforcements off Huron Parkway, we provide tailored groundwork that withstands Michigan’s freeze-thaw cycles and heavy traffic loads.

FREQUENTLY ASKED QUESTIONS
Ann Arbor, MI FOUNDATIONS FAQ
What soil conditions affect foundation construction in Ann Arbor?
Ann Arbor has a mix of clay, loam, and sandy soils that expand and contract with moisture changes. This movement can affect stability, so proper grading, drainage, and reinforcement are key during foundation and wall construction. Our team evaluates each site’s soil profile to prevent cracking or shifting over time.
Are permits required for foundation or concrete wall work in Ann Arbor?
Yes. Most new foundations, additions, or structural concrete work require permits from the City of Ann Arbor’s Building Department. Permit details and inspection steps are managed through the Building, Rental, and Inspection Services office.
How does Ann Arbor’s weather impact concrete foundations?
Ann Arbor’s freeze-thaw cycles and seasonal moisture changes can stress concrete if it’s not properly engineered. We use techniques and materials designed to handle Michigan’s temperature swings, ensuring strength and long-term performance through every season.
What areas around Ann Arbor do you serve for foundation and concrete work?
We handle projects throughout Washtenaw County — including Saline, Ypsilanti, Chelsea, Dexter, Scio Township, Pittsfield Township, and nearby communities like Canton and Plymouth.
